Stephen Kahler

Stephen Kahler received his B.S. degree in physics from the Ohio State University in 1961. He did graduate work on solar energetic (E > 10 MeV) particles (SEPs) at the Space Sciences Laboratory of the University of California at Berkeley and received his Ph.D. in physics in 1968. Post-doctoral work at the Naval Research Laboratory in Washington focused on solar X-ray flares. A position at American Science and Engineering in Cambridge MA involved work on the AS&E solar soft X-ray telescope on the NASA Skylab spacecraft, primarily analyzing X-ray image data of solar flares and solar coronal holes. He joined the Air Force Research Laboratory (AFRL) at Hanscom AFB in 1980 as a National Research Council Research Associate and as a contractor before becoming an AFRL employee in 1992. His work there has focused primarily on SEP events, coronal mass ejections (CMEs), and the topology of the interplanetary magnetic field. Various appointments held include an NRC research associateship at NOAA in Boulder, CO; an NSF exchange scientist at the Ioffe Physical-Technical Institute in St. Petersburg, Russia; and a visiting professor at the University of Nagoya in Japan. In 2011 he relocated with the AFRL Space Vehicles Directorate to Kirtland AFB in Albuquerque. Current work involves research on SEPs and space weather forecasting models. Dr. Kahler is a member of the American Astronomical Society, the International Astronomical Union, and the American Geophysical Union.
